Patent GB-486050-A (GB)
Title: Improvements in or relating to fluid-blast electric circuit breakers
IPC: H01H33/98
Filed: 1937-02-02
Abstract: 486,050. Fluid - blast switches. GENERAL ELECTRIC CO., Ltd., and KEELEY, F. J. Feb. 2, 1937, No. 3068. [Class 38 (v)] In a circuit-breaker of the kind in which contact is made and broken between complementary contacts in an insulating fluid in a pot or chamber, circuit - interruption being effected at two or more series - connected breaks and the pressure produced by arcing at one break being used to quench the arc at the second break, the contacts of which separate prior to those of the first break, a single longitudinally-moving intermediate contact-member forms one contact of both breaks, the complementary contact of the first break comprises a rocking or pivoted contact disposed in the pot or chamber, and the complementary contact of the second break comprises a contact-rod adapted to extend into the pot or chamber, the second break being arranged to occur adjacent an aperture in the wall of the said pot or chamber. The Figure shows the closed position of an oil-immersed circuit-breaker having an insulating cylinder 5 provided with an aperture 10 and a horizontal shelf 11, above an aperture 13 in which a sleeve 16 is secured, the intermediate contact 17 being slidable in the sleeve to an extent limited by a head 18. A co-operating contact 19 is pivoted to a bracket 20 and linked at 21 to a collar 22 on an insulating tube 23, which is slidable in holes in the metal plate 4 and pot 5. This tube is normally biassed by spring 24 in a direction to separate contacts 18, 19, but the bias is overcome by a stronger spring 25 acting between the closed upper end of the tube and an insulating plunger 26 which is pressed upwards by the cross-bar 9. When the circuit is opened, the spring 25 raises the tube 23 and causes contacts 19, 18 to follow the contact-rod 15, until the head 18 engages the sleeve 16, whereupon 15 separates from 17 and draws an arc adjacent aperture 10. Before this arc can attain a great length, the plunger 26 is arrested by a shoulder 27 thereon engaging the tube 23, whereupon spring 24 forces the tube 23 downwards and separates 19 from 18. The arc thus produced sets up a pressure which drives oil downwards to put out the arc between the lower contacts.

Title: Laser
IPC: G02F1/01
Filed: 1973-01-22
Abstract: 1409975 Resonance cells INTERNATIONAL BUSINESS MACHINES CORP 22 Jan 1973 [22 May 1972] 3107/73 Heading G6P [Also in Division H1] A mode-looked laser is Q-switched by a caesium or rubidium gas absorption cell which becomes light transmitting when the gas is ionized sufficiently for a charged condenser to discharge through the cell. The absorption cell may be controlled by a charged condenser potential insufficient by itself to cause transmission of light, but effective when the cell is simultaneously irradiated by a further laser, Figs. 1 and 4. Alternatively the cell may be switched directly into the conductive state by the application of a sufficiently high charged condenser potential, Fig. 6. In Fig. 1 the laser comprises dichroic resonator mirrors 8, 10, an optically-pumped neodymium glass laser rod 2, a mode-locking dye cell 12, and a heated caesium gas absorption cell 18, both the laser rod and the absorption cell having Brewster angle end surfaces 4, 6 and 20, 22. The laser produces 1À06 Á mode-locked output pulses when the absorption cell is made light transmissive by pulses from an opticallypumped 0À69 Á ruby laser 16 which may be giant pulse or mode locked, the 0À69 Á pulses ionizing the caesium vapour sufficiently for a charged condenser 27 to discharge through the cell. Synchronism of laser pumping is obtained by detecting the ruby laser output from a beam splitter 30. The embodiment of Fig. 4 is not shown, but is identical to that of Fig. 1 except for the use of rubidium instead of caesium and a reversal of the active media for the two lasers. In Fig. 6 the charged condenser 27 has a potential sufficiently high to ionize the absorption gas directly when a spark gap switch or thyratron 60 is activated by pulsing a transformer primary winding p. The arrangement of Figs. 1 or 4 may have its output applied to a laser amplifier the optical pumping of which is synchronized, with a suitable delay, with the pumping of the other two lasers. The absorption cell is shown in Fig. 3 and comprises an insulated alumina tube 44 sealed by stainless steel housings 42, 44 with Brewster windows 20, 22. The electrodes 46, 48 are welded to respective rolls of stainless steel mesh 36, 38 and the assembly is heated by an asbestos-coated heating tape 50. The tube may contain caesium vapour at a pressure of 1 to 20 torr.
